Abstract
As the main component of barrel weapon, the wear of barrel is a key factor of its service life. In this study, the typical barrel material is selected as the research object. Firstly, through theoretical analysis, the contact stress on the barrel inner wall generated by the extrusion of projectile is obtained. According to the calculation result, the load parameters of the wear test are determined. Then, the high-temperature wear tester is used to study the wear properties of the chrome-plated steel with different matrix hardness at high temperature. Finally, the wear scar profile, the wear surface, the cross section and the subsurface hardness have been analyzed. The test results show that the failure mechanism of high-temperature wear of chrome-plated steel with different matrix hardness is different. By increasing the hardness of the matrix, the high-temperature wear resistance of gun barrel material can be improved.
